1、先创建my.cnf文件
    在目录~/data/work/data/mysql/ 下先创建文件

    1. ➜  mysql touch my.cnf
    2. ➜  mysql ls
    3. data   my.cnf var
    4. ➜  mysql

    2、 docker-compose.yml文件的

    version: "3"
services:

  mysql:
      image: mysql:5.7 
      container_name: sc-mysql
      restart: always
      networks:
       - sc-net
      ports:
       - 3306:3306
      volumes:
       - ./mysql/data:/data
       - ./mysql/logs:/logs
       - ./mysql/conf:/etc/mysql/mysql.conf.d
       - ./mysql/var/lib/mysql:/var/lib/mysql
       - ./mysql/mysqlBackup:/data/mysqlBackup
      environment:
       TZ: Asia/Shanghai
       MYSQL_ROOT_PASSWORD: root123
       command: --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci
networks:
  sc-net:
    external: false

    3、在 docker-compose.yml 所在目录，执行命令

    sudo docker-compose up -d
